Life-history theory predicts that animals face a trade-off in energy allocation between performing strenuous exercise, such as migratory flight, and mounting an immune response. We experimentally tested this prediction by studying function European starlings, Sturnus vulgaris, flown wind tunnel. Specifically, we predicted constitutive decreases response to training and, additionally, immediate exercise. compared among three groups: (1) 'untrained' birds were kept cages not flown; (2)...
The nonbreeding distribution of Western Sandpipers (Calidris mauri) was documented using 19 data sets from 13 sites along the Pacific and Atlantic coasts Americas. showed latitudinal segregation with regard to sex age. Females wintered farther south than males. A “U” shaped pattern found respect age, juveniles occurring at higher proportions both northern southern ends range. Distribution sexes might be affected by differences in bill length a trend depth prey. For age class distribution,...
Summary Migratory birds have been implicated in the spread of some zoonotic diseases, but how well infected individuals can fly remains poorly understood. We used western sandpipers Calidris mauri to experimentally test whether flight is affected when long-distance migrants are mounting an immune response and maintain defences during a wind tunnel. measured five indicators innate immunity ‘flown-healthy’ (flying tunnel without response),’flown-sick’ while acute phase response, which part...
Bar-tailed Godwits (Limosa lapponica) are long-distance migratory shorebirds. About a third of the global population migrate to Australia during non-breeding season where they occur mainly in north-west and east. Using measurements bill, wing, tarsus total-head (head bill), we show that birds from two main Australian regions belong separate populations. Individuals north-western subspecies L. l. menzbieri, which breeds north-eastern Russia, whereas those south-eastern baueri, northern...
Differential migration involving intraspecific segregation of ages or sexes on the non-breeding grounds is common among migratory birds. Most existing data have, however, been collected in Europe and Americas very little known about such patterns East Asian—Australasian Flyway, which links eastern Siberia with Australia New Zealand. Spatial males females during at has clear implications for conservation management, as loss habitat predominantly used by members one sex will disproportionately...
Boreal caribou (Woodland Caribou, boreal population; Rangifer tarandus caribou) is a prominent mammal at the heart of decades-long conflict between growing resource sector and associated risks to biodiversity. We employed ISO 31010 Bow-tie Risk Assessment Tool (BRAT) evaluate cumulative effects anthropogenic natural factors that may affect risk self-sustainability herds Northeastern British Columbia. used BRAT produce visual synthesis causing growth rate persistently fall below level...

ABSTRACT Differential distribution of nonbreeding Least Sandpipers (Calidris minutilla) according to sex, bill, and wing length was documented using capture data from six locations between California Ecuador. The age classes did not vary with latitude. Females, which are slightly larger than males, migrated further south. Wing increased toward the south for both males females, is consistent notion that longer wings adaptive migrations. Bill also in sexes north A latitudinal cline prey...
In differential migrants the members of different age-classes or sex travel to geographically separate non-breeding areas. Here, we test five competing hypotheses explaining migration using more than 40 000 records 22 species shorebirds (Charadriiformes) occurring at two areas distance from breeding grounds and that also differ in climate. We showed across species, larger was abundant south-eastern north-western Australia. Size, as indicated by wing-length, greater south-east north-west for...

The boreal zone is at risk of cumulative effects natural resource extraction activities, which may be further exacerbated in the face climate change. A major challenge lack common approaches to assess effectiveness management measures (e.g., acts, regulations, standards, guidelines, best practices and certification systems) determine if policy objective sustainable being met.

We documented vocalization activity of breeding shorebirds at two sites in northern and western Alaska, on the Colville River Delta Yukon Kuskokwim Delta. At both sites, number calling individuals decreased throughout season. Variation was significantly higher towards end season, while weather variables affected only Our results highlight importance timing, weather, site-specific attributes birds detected. discuss our findings context different methods to monitor shorebirds.
Abstract Identifying genetic conservation units (CUs) in threatened species is critical for the preservation of adaptive capacity and evolutionary potential face climate change. However, delineating CUs highly mobile remains a challenge due to high rates gene flow signatures isolation by distance. Even when are delineated species, often lack key biological information about what populations have most need guide management decisions. Here we implement framework CU identification Canada...
Population sex ratios in monogamous birds are often male biased. One factor that can affect population is sex-biased predation. However, most estimates of predation have focused on species with obvious sexual colour dimorphism or body size dimorphism. Data sexually monomorphic generally lacking. In the present study, we adopt a PCR-based sexing procedure to help test for wintering western sandpipers (Calidris mauri), shorebird shows only subtle Specifically, by comparing priori determined...
